Measurement System for Evaluating the Swallowing Process And/or for Detecting Aspiration

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a measurement system that evaluates the swallowing process, particularly the closure of the airway during swallowing and the detection of aspiration (when non-gaseous substances like food or liquid enter the airway). The system uses bioimpedance measurements via electrodes placed in specific positions on or near the neck to monitor these physiological events. It provides real-time, non-invasive detection and assessment of swallowing function and aspiration risks, supporting diagnosis and therapeutic intervention for people with swallowing disorders (dysphagia).

Use CasesContent extracted from patent full text and abstract with AI.

• Screening patients with suspected swallowing disorders (dysphagia) in hospitals, rehabilitation centers, or nursing homes.
• Real-time monitoring of swallowing safety in high-risk populations, such as post-stroke patients or the elderly.
• Assessing whether a patient can safely consume food or liquid orally, thereby reducing the risk of aspiration pneumonia.
• Providing feedback and progress tracking during swallowing therapy and rehabilitation exercises for speech-language pathologists and therapists.
• Long-term, unattended monitoring of swallowing and aspiration in home-care settings or during routine care.
• Integration into implantable neuroprosthetic devices for continuous support and intervention in severe cases.

BenefitsContent extracted from patent full text and abstract with AI.

• Non-invasive and safe, avoiding exposure to harmful radiation (unlike fluoroscopy) or invasive procedures.
• Allows real-time, immediate results, facilitating faster clinical decisions.
• Can be operated by non-specialist healthcare staff, reducing the need for expensive, highly trained personnel and specialized equipment.
• Portable and easy to use, enabling broader access in various care environments, including outpatient and home settings.
• Supports continuous or repeated monitoring without patient discomfort.
• Provides objective and quantifiable feedback for both diagnosis and therapy progress.
• Potential to trigger therapeutic actions (such as electrical stimulation or cough reflexes) upon detection of dangerous events (e.g., silent aspiration), reducing complication risks.

Patent Abstract

The invention relates to the use of a measurement system for evaluating a swallowing process, preferably a closure of the airway during the swallowing process and/or an aspiration. The measurement system can be used for supporting therapy in case of swallowing disorders and/or for diagnosing changes in the swallowing sequence.
